Seismic effects in different rocks and soil

Some studies into seismic effects produced by blasting in extraction panels nearby guarded objects are discussed. Procedures developed at the Institute of Mining of the Ural Branch, Russian Academy of Sciences for the protection of guarded objects from blasting impact depending on net explosive mass per delay interval, earth pressure coefficient and maximum allowable PPV. The author describes approaches to drilling-and-blasting designs depending on wave process behavior in different soil conditions. The long-term data analysis of different geological conditions is presented. The measurements were compared with calculated structural weakening of rock mass, which allowed identifying some relationships agreeable with the actual behavior of wave processes in various soils. These relationships are approximate though the approximation principle, given appropriate development, can be very significant regarding safety of mining. The promising areas of the near future research into seismic events and blast-induced load in rocks are proposed.
